before 900; (noun) Middle English,Old Englishhors; cognate with Old Norsehross,Dutchros,GermanRoss (Middle High Germanros,Old High Germanhros); (v.) Middle Englishhorsen to provide with horses, Old Englishhorsian, derivative of the noun

Old English hors, from Proto-Germanic *hursa- (cf. Old Norse hross, Old Frisian hors, Middle Dutch ors, Dutch ros, Old High German hros, German Roß "horse"), of unknown origin, connected by some with PIE root *kurs-, source of Latin currere "to run" (see current (adj.)).

The usual Indo-European word is represented by Old English eoh, from PIE *ekwo- "horse" (see equine). In many other languages, as in English, this root has been lost in favor of synonyms, probably via superstitious taboo on uttering the name of an animal so important in Indo-European religion.

Used since at least late 14c. of various devices or appliances which suggest a horse (e.g. sawhorse). To ride a horse that was foaled of an acorn (1670s) was through early 19c. a way to say "be hanged from the gallows." Slang for heroin is first attested 1950. Horse latitudes first attested 1777, the name of unknown origin, despite much speculation. Dead horse as a figure for "something that has ceased to be useful" is attested from 1630s.

HORSEGODMOTHER, a large masculine wench; one whom it is difficult to rank among the purest and gentlest portion of the community. [John Trotter Brockett, "A Glossary of North Country Words," 1829]

The horse's mouth as a source of reliable information is from 1921, perhaps originally of racetrack tips, from the fact that a horse's age can be determined accurately by looking at its teeth. To swap horses while crossing the river (a bad idea) is from the American Civil War and appears to have been originally one of Abe Lincoln's stories. Horse and buggy meaning "old-fashioned" is recorded from 1926 slang, originally in reference to a "young lady out of date, with long hair." The proverbial gift horse was earlier given horse:

No man ought to looke a geuen hors in the mouth. [Heywood, 1546]

The modern form perhaps traces to Butler's "Hudibras" (1663), where the tight iambic tetrameter required a shorter phrase:

He ne'er consider'd it, as loth To look a Gift-horse in the mouth.

v.

Old English horsian "to provide with a horse or horses," from horse (n.). Related: Horsed; horsing. Sense of "to play excessive jokes on" is by 1893, mostly in formation horse around (1928), perhaps from horseplay.

[A] favorite pastime for many men is to "horse" or guy a friend who has shown himself susceptible to ridicule or fun making. "Horsing" is extremely wholesome mental discipline for over sensitive or super-conceited young men. "Horsing" always implies a joke at another's expense. As to how it came into use there is no satisfactory theory to offer. ["Yale Literary Magazine," December 1893]

[the sense ''heroin'' may have derived fr shit, ''heroin,'' by way of horseshit, although the derivation might well have gone in the other direction; or perhaps the sense is based on the sobriquet of a Damon Runyon character Harry the Horse by way of the partial rhyme of Harry with heroin; second verb sense used of stallions and mares by 1420]

horse in the Bible

always referred to in the Bible in connection with warlike operations, except Isa. 28:28. The war-horse is described Job 39:19-25. For a long period after their settlement in Canaan the Israelites made no use of horses, according to the prohibition, Deut. 17:16. David was the first to form a force of cavalry (2 Sam. 8:4). But Solomon, from his connection with Egypt, greatly multiplied their number (1 Kings 4:26; 10:26, 29). After this, horses were freely used in Israel (1 Kings 22:4; 2 Kings 3:7; 9:21, 33; 11:16). The furniture of the horse consisted simply of a bridle (Isa. 30:28) and a curb (Ps. 32:9).
